Abstract (en)
[origin: WO2015082148A1] The invention relates to a device (1) for actuating a hydraulic piston (23) for an electrically actuatable clutch in a motor vehicle. An electric motor (3) cooperates with a force transmission arrangement (5), in order to generate a force acting in a linear direction for actuating the hydraulic piston (23). The force transmission arrangement (5) comprises a drive gear segment (7) and a guide arrangement (9). The drive gear segment (7) is provided with toothing (13) on at least part of its circumference, and is rotatably arranged about a first bolt (15). In addition, a second bolt (17) is provided on a lever arm (33), said second bolt being arranged eccentrically in relation to the first bolt (15). The guide arrangement (9) comprises a first elongated hole (19) and a second elongated hole (21) arranged at a right angle to the first elongated hole. The elongated holes (19, 21) and the bolts (15, 17) are arranged in such a way that the guide arrangement (9) is moved in a linear direction when the drive gear segment (7) is rotated by the electric motor (3).
